Millions of smoke/carbon monoxide detectors recalled due to failure to chirp

The United States Consumer Product Safety Commission says the alarms can fail to continue to chirp when they reach the end of their seven-year life, leaving people to believe they’re still working. This poses a risk of consumers not being alerted to a fire or carbon monoxide incident in their home.

The approximate 3.6 million alarms included in the recall have the model number KN-COSM-IB. The alarms were manufactured between June 1, 2004 and December 31, 2010. They are hard-wired into a home’s electric power.

The CPSC says Kidde has received eight reports of incidents with the recalled alarms. No injuries have been reported.

Consumers should immediately stop using the recalled alarms and contact Kidde directly for a replacement.
